BOTTLE FOR AERATED LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 701,968, dated June 10, 1902.

' Application filed July 16. 1901. Serial No- 68A87. (N model.)

, which are designed to maintain the bottle sealed by gaseous pressure. I

The object of this invention is to release the stopper from the mouth of the bottle.

Where aerated-liquid bottles are sealed by a ball-valve held in its seat by gaseous pressure it is necessary to press the ball down in order to permit the liquid or beverage to be poured out, and this is usually done by introducing the finger in the neck of the bottle or by using an instrument, which is not only troublesome, but inconvenient.

This invention is designed to release the pressure which holds the ball-stopper in its seat by allowing it to escape through a valve, so that the ball can precipitate. Referring to the drawings accompanying and forming part of this specification, Figure 1 is an elevation of the bottle, and Fig. 2 is a vertical section thereof.

Similar characters of reference indicatelike parts throughout thedrawings.

A is a bottle in the wall of which and near the mouth thereof is an internal projection 1), formed by an inturned portion of the Wall, and the inner extremity of this projection forms an annular valve-seat within and beyond the wall of said bottle and at the same time provides a recess a on the outside which serves as a guard or shield for the stem of the valve. This valve is composed of three parts-viz., a rod cl, a valve-head e, secured on the inner end thereof, and a knob c on the outer end, which is sufficiently large to prevent said rod and valve from falling into the bottle. Disposed on this rod and between the annular seat and the head e is a packing-ring e, which forms an air-tight joint when the valve is held in position against said seat by the pressure. I

At the outside of the bottle A the opening formed by the inturned projection 12 is large enough to accept the finger, so that the rod d, which is within this opening, may be pressed in so as to relieve the valve 6 from the seat to emit the gas, whereby the pressure is taken from the ball-valve,'so as to permit its precipitation, in order to pour out the contents of the bottle. 3

The mouth of the bottle is provided with an annular seat, formed by a resilient ring 1', against which a ball-stopper j is maintained by pressure when the bottle is filled. On the interior of the wall of said bottle is an interceptor f, which prevents the ball-stopper from running down into the mouth whenthe bottle is upturned to 'emit the liquid. To prevent the ball-stopperj from falling to the bottom of said bottle, the wall thereof on op posite sides is provided with interior projectionsg, which form a bridge. When the bottle is filled, the stopper is held against its seat in the mouth thereof. To unseal the bottle, the knob o is pushed in, which will release the valve e from its seat, whereby the gaseous pressure will escape and allow the ball-stopper j to precipitate to the projections g, when the contents of the bottle can be poured out, and the interceptor f will prevent said stopper from rolling into the mouth of the bottle vand obstructing the passage of the liquid.

It will beobserved that the neck of the bottle, which terminates, as usual, in a mouth, is provided with an integral reflex nipple, said nipple consisting of an outwardly-pro jecting base portion a and an inwardly-projecting reflex portion b d within and forming a continuation of said base portion, a valve 6 e being seated upon the end of said inwardly projecting nipple, and that a stem rigid with said valve and provided with a head a is housed wholly within said reflex nipple.

It is understood that the Valve may be applied to any part of the bottle whichpractical experience will suggest. It,.will-beseen that this valve is held in position against its seat by gaseous pressure and that when man ually operated or pressed away from its seat the gas will discharge and permit the stopper to precipitate. It will be noted that the Valve is only confined to its seat during pressure and is loosely mounted in the opening,

so as to permit proper cleansing thereof when the bottle is being washed. It will be observed that the opening of the valve may be more easily effected by lateral pressure upon the stem, which, as is obvious, will cause a tilting of the valve g, thus allowing the gas to escape. It will also be observed that the stem of this valve is protected within an outwardlyprojected portion of the bottle-wall, so that there is no danger of accidental contact with the stem to unseat the valve, especially when the bottles are packed close together.

I claim- 1. A bottle having a mouth and also having at a separate point a reflex integral nipple, said nipple consisting of an outwardlyprojectingibase portion and an inwardly-projecting reflex portion Within and forming a continuation thereof, and adapted at its inner end to form a seat for a pressure-valve.

2. The combination with a bottle having a mouth and also having at aseparate point a reflex integral nipple, said nipple consisting of an outwardly-projecting base portion and an inwardly-projecting reflex portion Within and forming a continuation thereof, of a valve having a yielding portion which seats upon the inner end of said nipple, and a stem rigid with said valve and provided at its outer end with a head.

3. The combination with a bottle having a neck terminating in a mouth, and also having in said neck an integral reflex nipple, said nipple consisting of an outwardly-projecting base portion and an inwardly-projecting reflex portion Within and forming a continuation thereof, of a valve seated upon the inner end of said nipple, and a stem rigid with said valve and housed wholly within said reflex nipple,

In Witness whereof I have hereunto set my hand in the presence of two witnesses.
